I don't know if this will help but I just spoke to a mechanic that was refered by a friend with great credentials.

He mentioned to me that he had a BMW that would always misfire after having the car tuned and he changed the spark plugs but he didn't put the platinum tips because he found that they overheat in those types of applications.
He put normal plugs and the car runs Amaaaaazing.

I don't know if this helps your case because your problem may not even be the spark plugs but I figured I'd share this info and see if maybe someone could shed light on it

well the real cost of ownership is of course more than price alone, somehow you need to figure out what each driven km cost you, and with the downtime you had while your car depreciates could probably be more than an GT-R (dont get me started on Stickys cost per driven km)

Which downtime? To change fuel pump, plugs, 1 injector and some sensors unnecessarily? Total cost of my attempted fixes was about $1k, total downtime for the car was maybe a couple hours (less than a day).

Do you know how much maintenance of the breaks for instance is on a GTR?

Anyways, great car, that's not the point and I was kidding when I said weak about his choice. What's your point?

I guess I am only trying to convince myself buying a 997tt isnt going to be to bad financially

Don't get me wrong. I didn't say buying a GT-R is a bad choice, far from it, same for the 997TT, both simply amazing cars, can't go wrong there. Slap a set of GT3071s on the 997TT (or the 996TT) and the car wakes up in a major way. GT-R, x-pipe+tune+E85 and you've got yourself a mid to low 10sec car if your tranny holds up. Daily driveability, interior, maintenance and insurance is what kills those for me though in those two cars, for now.

I havent driven the GT-R but the interior wasnt in my taste either, the 997 came with extended leather dash etc and its a nice place to be, the 997.2 got a nicer steering wheel but a weaker engine, daily driveability is just fine imo, I do the school runs with it and my grocery shopping. the 997 has a 2-y service interval, I guess I'll find out just how bad it is next year. Insurance is (for me in Stockholm) $2000/year only a few hundred $ more than my 335i was.

I heard that the DCT in the GT-R has a very expensive maintenance schedule that my manual 997 hopefully spares me from...

I ran into a GT-R owner at a gas station this summer and he mentioned around $7K for a brake job on his GT-R

@Big Tom , let us know if you need a Cobb AccessPort for your GT-R along with their TCU reprogramming. We also carry the full line of products from AMS in case you're interested in an Alpha kit for it looking forward to some vids!

That's good to know buddy!

I'm still planning on which mods I'll install, but I'm leaning towards COB, Feritta complete exhaust, some sort of an antake and e85 conversion kit (fuel pump and injectors).
